This video summarizes important inventions of the first Industrial Revolution, where mechanization and new energy sources were utilized.  Thomas Newcomen developed the first practical steam engine that was used to pump water out of coal mines, and in 1776 James Watt improved on Newcomen’s concept where he enabled steam power to be used in many more types of applications;  In 1870, James Hargreaves improved the “Spinning Jenny” device, which improved the productivity of textile workers by eight times;  In the 18th century, Henry Cort developed a method of working with high-quality molten iron called “puddled iron” which was also mechanized using steam engines.
